JetVentFans Smart Technology, Advanced Innovation & Design

How It Works

Smart Technology

The JetVent Control Center offers significant energy savings through comprehensive ventilation management. The Control Center communicates with JetVent fans, integrated sensors, supply fans and exhaust fans to dynamically control the rate of ventilation according to the CO or NO₂ pollutant levels, temperature, or smoke in the space. This control system costs less to install, is simple to commission, and easy to monitor.

Advanced Innovation

An innovative alternative to traditional ducted systems, Induction Ventilation Systems are comprised of a series of high-velocity JetVent fans that improve ventilation, save energy, and offer sophisticated communication, management and alarm notification. The JetVent Fan system utilizes the latest in EC motor technology with integrated speed control and connected sensors. The many advantages of Induction Ventilation Systems with JetVent Fans is driving a rapid expansion of installations throughout Europe, Asia, Australia and the United States.

Practical Design

The low-profile design of these induction fans can result in significant savings in excavation and construction costs. JetVent Fans are engineered to perform when mounted at the ceiling in-between support beams. This height savings can be the critical difference in providing ventilation for parking garages. In new construction, the cost savings from reduced ceiling heights can be particularly significant in multi-level structures.

Saves Energy

Dynamic management of the ventilation system based on actual pollutant levels generates significant energy savings. The ventilation system runs dramatically less, at lower speeds, while safe ventilation levels are maintained.

Technology-Driven Energy Savings with JetVent Fans

JetVent Fans EC motor’s infinite speed control allows for an unprecedented level of precision in ventilation.

How It Works

A JetVent Fans Induction Ventilation System operates on well-proven principles of longitudinal tunnel ventilation engineering. The fans produce a high-velocity jet of air which, in turn, moves a larger quantity of air surrounding the fans through a process known as entrainment. The amount of air entrained by a fan increases with the velocity and the quantity of air that is discharged by the fan. These characteristics relate directly to the thrust rating of the fan, which is measured in Newtons (N).

The propulsive force of a jet required to accelerate one kilogram of mass at the rate of one meter per second squared in the direction of the applied force, measured in Newtons (N).

Drawing Up the Plan

A good starting point for an initial ventilation plan is to do a “thrust per square foot” analysis for each floor of the facility. Based on the layout and any potential construction constraints, determine the fan model, how many, and where to place them. Then it’s onto sensors, detectors and controls. Once a design is drafted, a CFD analysis can confirm system performance and identify potential opportunities to enhance airflow and ventilation patterns by adding, subtracting, or relocating fans.

Advantages of Induction Fans versus Impulse Fans and Ducted Systems

The low-profile design of induction fans saves up to 8'' per floor of excavation and other construction costs over impulse fans and ducted systems. The number of induction fans required can be up to 70% fewer than the number of impulse fans required to do the same job, yielding considerable installation cost savings for induction fans. Ducted systems are also significantly more expensive to install than induction ventilation systems. Induction fans intake from below and exhaust at a downward angle, making them effective when mounted directly to the ceiling, within cross-beams, whereas impulse fans require more clear line-of-site for mounting, which means higher ceilings are required. Because of the back-pressure that builds in ducted systems, they require much larger supply and exhaust fans than induction ventilation systems.
